characterized by low cost of operation, simplicityin construction; and otherwise fully capable of serving both as a cooking stove and as a heater.

A further object of the invention is to provide l an electric s'tove of the character above mentioned. I

The invention, together with its objects and advantages will be best understood from astudy of the following description taken in connection with the accompanying drawings, wherein:

Figure 1 is a vertical sectional view through a stove embodying the features of -the present invention.

Fig. 2 is a horizontal sectional view through the stove.

Fig. 3 is a vertical transverse sectional view Referring to the drawings by reference numer- A als, it will be seen that in accordance with the present invention, the stove, mounted on suitable legs 5 embodies an outer casing or shell 6, the bottom and vertical walls of which are insulated as shown, while the top wall 1 is formed of metalv or other suitable material which will heat rapidly and cool within a relatively short space of time.

Suitably mounted within the shell or casing 6 of the stove and spaced from the walls of the casing at the top, bottom and ends thereof, is an oven 8 to which access is had through the medium of a suitably provided door 9 at the front of the stove. Suitably mounted Within the stove casing 6 at one en'd of the latter and spaced from opposite side walls of the casing and from the bottom wall of the casing is a vertical air duct l0 that at its lower end is Vprovided with an enlarged bellshaped inlet il. At the top thereof, the duct Il is provided with an outlet n that opens into the space between the top 1 of the casing and the.

top of the oven l.

Interposed between the adjacent end walls of othe casing 6 and the air duct Il! is a block I4 of insulating material which-accommodates the wires that connect an electric switch l5 suitably mounted on the said end wall of the casing 6 with a plurality, in the present instance four, of f vertically disposed electric heaters or resistance wires I6 suitably mounted within the air duct I0 as shown. y

`Mounted on a suitable shelf or platform `l1 supported on the aforementioned end wall of the stove casing 6 is an electric motor I8, the arma- 5 ture shaft of which extends inwardly to termi- .nate within the inlet mouth II of the air duct l0, and on said end of the motor shaft is a fan i9 which serves to cause a forced circulation of air through the duct Wand within the casing 6 10 around the oven 8. Obviously the air in passing through theduct lll is heated through the medium of thefheating coils I6.

When it is desired to concentrate the heated air at the top of the stove for heating the top 1 16 to a degree suilicient to permit use of the stove for cooking purposes, a valve 2| is closed. Valve 2| as shown, extends between the front and rear walls of the stove casing 6 and is arranged within the space between the end wall of the easing 6 20 farthest remote from the heater and the con-A fronting end wall of the oven 8, being hinged to-the said end wall of the casing 6 to swing in the direction indicated by the arrow in Fig. 1.

' Provided on the confronting end Wall of the oven 25 `neath the top 1 of the casing will strike the closed valve causing a back pressure of this heater air 35 at the top of the stove resulting in the top i1 of the stove becoming very hotso that thev stove can be used forcooking purposes.

Also, when it is desired t0 'concentrate the heat in a manner to heat onlya portion of the 40 Y top l valve 24 is swung to a closeclposition, The valve 24 is disposed within the space/between the top 1 of the stove casing G and the top of the g oven 8 and is mounted so as to swing vertically to open and closed position. .l Swinging movement of the valve 24 to the closed position is limited by a stop 25 pivotally provided on the VunderV side of the top 1 of thestove casing and the valve 24 is manipulated from the front side of the'stove through the medium of a knob 2i -provided on 50 vided therefor within the opening 3d. Obviously rod 28 that extends transversely of the stove casing from the front to therear thereof while for the other of the valves 21 there is provided ar tubular shaft 29 which accommodates the shaft 28. For the shafts 28 and 29, there are provided at the front side of the stove manipulating knobs 30 and 3|. Thus it will be seen that the valves 21 areoperable independently of one another and when in closed position have their free end edges abutting against the adjacent end wall of the oven 3 as shown in Fig. 4. It will also be apparent that when valves 21- are closed, the hot air issuing from the outlet I3 of the duct I0 will be prevented from flowing back, the heated air,

with valves 21 closed being caused to iiow through the space between the top 'l of the stove casing 6 and the top of the oven to circulate as permitted by the position of adjustment of valves 2l and 2d. When the hot air is to be used for heating a room or the like, said hot air is permitted to issue' from the stove casing through an outlet 32 provided in the end wall of the casing 6 farthest remote from the air duct Il! and above the valve 2i. For the hot air outlet 32 there is provided a suitable closure 33.

Also the end wall of the casing 6, on which is mounted motor I8, is provided with a cold air inlet 34 through which the air from the room or surrounding atmosphere may pass into the stove casing to be heated in its circulation through the stove casing. For controlling the opening 341, there is provided interiorly of the stove casing, and as shown, a valve plate 35.- Plate 35 is mounted on the inner end of lan adjustment bolt 36, the threaded shank portion of which threads through the hub of a supportingspider' 31 pro- From the above n; wm be seen that I have.A

provided :an electric stove whichA may be used, with facility, for either cooking, or heating purposes, or both, as may be found desirable.

It is thought that a clear understanding of the n construction, utility, operation, and advantages from corresponding walls of said casing, an air duct arranged within the casing and disposed hot air outlet end opening into the space between g of Aa stove embodying the features of the present invention will be had without a 'more detailed description.

Having thus described the invention, what is g within the space between an end wall of the casing and the adjacent end wall of the, oven." said duct being of a width less than the width of said end wall of the casing to provide v.air passages communicating'between the top'and bottom ofthe casing independent of the duct, valvesforrsaid passages, said air duct having an inlet end disposed adjacent the bottom of the casing, and a driven fan arranged within the air the top of the oven andthe top of said casing, means for causing a forced circulation of vair through said duct, and an electric heating device arranged within said duct.
